Custom Resolution Utility (CRU)

[Aidorin]

Hi,

First of all, thanks for this utility, although I have not used it yet, it seems very interesting.

But I have some doubts and precautions, because I bought a new LG CX55'' TV that has cost me € 1,200 and I don't want to break it or damage it:

Does this CRU change or affect the internal software of the TV (as It seems), or does it only affect the PC/Nvidia driver side? And if it affects the TV software (as it seems), is there any risk that it will break it or affect the TV warranty?

I'm interested in this CRU because I use my LG CX55 '' with an RTX 3080, and I'm interested in reducing motion blur that occurs when playing at 60FPS. And I read this post on Reddit yesterday about this utility:

"...But in reality there is a big, important difference - Nvidia is doing frame doubling even when the adaptive sync range isn't wide enough to cover all framerates. So if your monitor's range is 90-144Hz, you will be playing 60 fps games at 120Hz! But if your monitor has a much more common 48-144Hz range, Nvidia will still prefer native 60Hz for 60fps, just like AMD.

Now, why does it matter? Unfortunately, monitors might not look the same at all refresh rates, especially 144Hz monitors. Many VA monitors look darker at lower refresh rates, and nearly all monitors have their overdrive settings optimized for maximum refresh rates. As a result, you may have two issues with adaptive sync at lower refresh rates:

-Brightness flickering (when the monitor is rapidly switching between high and low refresh rates)
-Ghosting/overshoot (trailing behind moving objects)"

I don't quite understand the logic or the procedure by which a game that runs at 60fps, goes to 120fps/hz, but as that post on Reddit says, it seems that Nvidia drivers what it does is double the fps. That seems that may will help eliminate or reduce motion blur, but before testing and learnig deeply how this CRU works, I want to know which risks there are, since my TV is new and expensive, and I don't want to break it or lose the warranty after the second week.

Thanks in advance, and lets see if I can finally find a way to reduce that motion blue at 60fps.
